In the realm of polymer science and manufacturing, ensuring the longevity and integrity of plastic materials is paramount. Degradation due to heat, oxidation, and processing can significantly compromise product performance and aesthetics. This is where the strategic use of antioxidants becomes indispensable. Among the various types available, phosphite antioxidants, particularly Antioxidant 168 (CAS 31570-04-4), stand out for their exceptional capabilities as secondary antioxidants.

As a leading chemical manufacturer and supplier, we understand the critical need for reliable and high-performance additives. Antioxidant 168, also known by its chemical name Tris(2,4-di-tert-butylphenyl) phosphite, is a cornerstone in polymer stabilization. Its primary function is to act as a hydroperoxide decomposer. During the high-temperature processing of polymers, autoxidation can generate hydroperoxides, which are unstable intermediates that can initiate further degradation chains. Antioxidant 168 efficiently converts these hydroperoxides into stable, non-radical products, thereby interrupting the degradation cycle.

The benefits of incorporating Antioxidant 168 into your formulations are manifold. Its hydrolytic stability is a significant advantage, ensuring that it remains effective even in the presence of moisture, a common challenge in manufacturing environments. Furthermore, its low volatility means it stays within the polymer matrix during processing, providing sustained protection without significant loss. This high thermal stability allows it to function effectively under demanding processing conditions, a critical factor for industries that process polymers at elevated temperatures.

A key aspect of Antioxidant 168's performance is its synergistic effect when combined with primary antioxidants, such as hindered phenols (like Antioxidant 1010 or 1076). While primary antioxidants scavenge free radicals directly, secondary antioxidants like Antioxidant 168 neutralize the by-products of oxidation. This dual action significantly enhances overall material stability, improves resistance to thermo-oxidative degradation, and extends the service life of the final product. This synergistic approach is crucial for achieving optimal performance and cost-effectiveness.

The applications for Antioxidant 168 are extensive, covering a wide range of polymer types and industries. It is widely used in polyolefins such as polyethylene (PE) and polypropylene (PP), as well as in engineering plastics like polycarbonates (PC) and polyamides (PA). Beyond these, it finds application in PVC, ABS resins, elastomers, adhesives, coatings, and petroleum products. Its ability to prevent molecular weight changes, such as chain scission and crosslinking, and to inhibit discoloration makes it an invaluable additive for manufacturers prioritizing both functionality and appearance.
